Speeiication of Letters Patent.

Patented June 9, 1914.

Application filed October 28, 1913. Serial No. 797,881.

To all whom it may concern Be it known that I, WILLIAM W. Snor.,

-citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain newT and useful Improvements in Irons, of which the following is a specification.

My invention relates to an ironfor do- `'mestie or laundry purposes, and it is designed to provide a simple and effective construction in which the maxim-um amount of heat may be delivered `to the ironing surface and with the least amount of waste of t-he heat.

The invention consists inthe features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In `the accompanying drawings, Figure 1 is a side elevation of anliron embodying my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a plan view of the lower or base member of theiron with the upper parts removed.` Fig. 4 is a transverse sectional view taken vertically of Figs. 1 and 2 about centrally thereof and looking from the right. Fig. 5 is an end view of the right hand end of Fig. `1.

In these drawings, l is the base member carrying the ironing surface on its lower face, this member beingof the general form of a tray and. having upwardly projecting side edges 2; a rear wall B and a front wall 4. IVithin this tray is a combustion chamber made up of a shell 5, the walls of which are integrally formed with the basemember so as to conduct the heat thereto from the burner tube 6, whicheXtends lengthwise of the combustion chamber,` about centrally thereof and about midway of its height. The combustion chamber or shell 5 is provided with an opening 7 in its top plate, extending from a point short of its rear end, through to the other end, as shown in Fig. 3. The shell forming the combustion chamber is open at its fro-nt end, as indicated at 8, in Fig. 2, and it is also open at its rear end because it terminates at the line 9 Figs. 2 and 3, leaving therefore a space between its rear end and the end wall 3. The shell forming the combustion chamber is, however integrally connected with the rear wall 3 bya block or metal portion 10, which extends across the rear `space and connects these parts; The combustion chamber, or rather the shell forming `the combustion chamber, terminates at the point 8, previously referred to, and is thus shorter thanV the base member 1, leaving a front space at 11 between the shell forming the combustion chamber and the front wall of the base. A post 12 rises in this space in line with the combustion chamber but sep.- arated slightly from the front end of the shell 5, this post being integrally formed with the base member as shown in Fig. 2. A top or cover member 13 is supported by studs integrally formed therewith, a pair 14. of these studs depending from the under side of the rear portion of the top plate or cover, and a second pair 15 depending from the cover or top plate at a point intermediate of its length. These studs rest upon a shield or diaphragm plate 16, which in turn rests upon the upper end of the post 12, and the upper surface of the reinforce or connecting piece 10. As shown in Fig. 2, the diaphragm or shield .member is therefore supported at a point above the shell composing the combustion chamber, and it over-lies the top opening of said combustion chamber and extends laterally to both sides of said opening, as shown in Fig. f1.

The top plate or cover has depending walls 17, which, as shown in Fig. f1, diverge from each other and conform substantially to the inclines of the side walls of the shell or combustion chamber 5, lying at a slight distance from the said shell as shown in Fig. 4. The lower edge of this depending skirt or wall of the top plate depends within and below the upper edge of the ange 2 of t-he base, being separated therefrom by a slight distance as indicated in Fig. 4t, this depending edge being marked 17. The skirt or depending wall of the top plate is also provided with a laterally extending flange 18, overlying and separated from the edge or flange 2 of the base. Openings 19 are provided in `the side wall of the top or cover member, these openings being disposed in a row on each side of the cover member near t-he top thereof. The partition or diaphragm 16 lies in the plane of the centers of these openings and at a slight distance below the top plate or cover.

The handle 20 has a bail 21 resting on lugs 22 projecting up from the top or cover plate. Bolts 23 hold the handle in place. These bolts `are screwed into the part 12 and the block l0 and they serve also to hold the top plate or cover in place as well as the shield or partition 16, clamping all these parts to-Y;

gether.

An opening 24 is formed in each side of the tray or base yat thefront part thereof, said openings communicating `with the interior spacel1. Openings are alsoformed in the rear wall 3 at 25, communicating with the space at 9 and with the interior of the combustion chamber which is also openY at its rear end below the integral part 10. Besides the free space 26 left at the rear between the top plate and the upper edge of the rear wall 3 of the base, as shown in Fig. 5, there is a free space also present between the skirt of the cover or top plate and the edge of the rearV wall.

'Ihe gas supply pipe is supported in the rear wall 3 and front post l2, and it has slits on its under side so that the gas flame will be thrown down and outwardly against the bottom and side walls of the combustion chamber. The walls of the combustion chamber have depending inner flanges 27 along the margin of the upper opening7, the purpose of which is to hold the heat and iiame within the combustionchamber so that there will be a maximum conduction of heatthrough the walls Vof thecombustion chamber to the base. The post l2 is in a position to receive the heat and iiamefromthe combustion chamber and this also acts to conduct heat to the base. The shield or diaphragm acts to retain theheat and flame in the combustion chamber, extending as it does over to opening 7, and it serves also to prevent the excessive heating of the top or cover portion of the iro-n. It prevents the direct impingement of the flame or heat against the top plate-and it provides for circulation of air above thef'diaphragm and between it and the top plate of the cover. At the same time the heat may escape from below the dia-` phragm or partition out through the side openings at the upper part of the side walls or skirt of the cover member.

The construction described'provides for 1 the proper circulation o-f the air and distri- Y to the base,'said shell being open at the top,

brition of heat. Air enters the rear openings and the front openings to aid combustion, and air is drawn Vin between the flanges 2 and 17 aiding combustion and preventing excessive heating of the skirt of the cover or top part of the iron. Air is also free to enter at the back through the vspace at the top and sides of the back wall.
